Description

Technical Field

[0001] This utility model relates to the field of hydraulic tooling technology for machining, specifically a modular hydraulic tooling for machining. Background Technology

[0002] Hydraulic tooling for machining refers to a device that uses a hydraulic system to position, clamp, and fix workpieces during the machining process. Hydraulic tooling controls the clamping and releasing of workpieces through hydraulic components (hydraulic cylinders, hydraulic pumps, etc.), thereby achieving automated and efficient machining. When it is necessary to clamp the workpiece, the hydraulic system generates pressure through the hydraulic cylinder to push the clamping device to fix the workpiece.

[0003] The invention disclosed in CN109571093A is a hydraulic tooling that can effectively and reliably clamp a flange, preventing it from moving during drilling. It can also use a multi-axis drill bit to complete the machining of all holes at once, resulting in high drilling efficiency. The second hydraulic cylinder can clamp and position the flange by retracting the pressure plate and the support. The clamping force of the second hydraulic cylinder is large, which can ensure the positioning rigidity of the flange. Then, the first hydraulic cylinder rises and relies on the first guide post to ensure the rising direction, which can disengage the flange from the positioning post.

[0004] However, the hydraulic fixtures disclosed above still have the following problems in actual use: Although the workpiece is positioned and clamped by the hydraulic components set in the fixture, such fixtures need to work together with multiple sets of hydraulic components during use. It is difficult to ensure the synchronous frequency during the operation of multiple sets of hydraulic components, which leads to clamping intervals and workpiece positioning deviation, affecting the subsequent machining efficiency of the workpiece.

[0005] We propose a modular hydraulic tooling for machining to address the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a modular hydraulic tooling for machining, in order to solve the problem that existing tooling uses hydraulic components set in the tooling to achieve workpiece positioning and clamping. However, such tooling requires multiple sets of hydraulic components to work together during use. It is difficult to ensure the synchronous frequency of multiple sets of hydraulic components during operation, which leads to clamping intervals and workpiece positioning deviation, affecting the subsequent machining efficiency of the workpiece.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular machining hydraulic tooling, comprising a support base and a drive cavity formed inside the bottom surface of the support base; further comprising:

[0008] The top surface of the bearing base is provided with a positioning mechanism, and the positioning mechanism includes a displacement clamping seat and a correction support seat.

[0009] The drive cavity on the bottom surface of the support base is equipped with a hydraulic mechanism, which includes a hydraulic cylinder and a hydraulic slide rod is slidably connected to the rear end of the hydraulic cylinder.

[0010] Preferably, the positioning mechanism includes a positioning groove, which is symmetrically opened on the left and right sides of the rear of the bearing base. A positioning rod is fixedly installed inside the positioning groove, and the positioning rod is slidably connected to the middle of the guide bracket.

[0011] Preferably, the bottom end of the displacement clamping seat included in the positioning mechanism is slidably disposed inside the positioning groove, and the displacement clamping seat inside the positioning groove is fixedly connected to the top end of the guide bracket, and the guide bracket is used to drive the displacement clamping seat to adjust its position in the front and back directions.

[0012] Preferably, the positioning mechanism includes a correction groove, which is symmetrically opened on the left and right sides inside the bearing base. The correction groove is slidably connected to the bottom end of the correction support, and the correction support corrects the deviation of the machining component during the positioning process by moving in the opposite direction.

[0013] Preferably, a support mechanism is provided in front of the top surface of the bearing base, and the support mechanism includes a support limiting seat. The support limiting seat is fixedly installed at the front center position of the top surface of the bearing base by bolts. The left and right sides of the top surface of the support limiting seat are elastically slidably connected to the lower end of the lifting slide rod. The bottom end of the symmetrically arranged lifting slide rod has an inclined structure and slides through the interior of the drive cavity.

[0014] Preferably, the supporting mechanism includes pressing protrusions, which slide through the upper end of the lifting slide rod, and the symmetrically arranged pressing protrusions are connected to the top of the lifting slide rod through elastic dampers.

[0015] Preferably, the hydraulic mechanism includes a hydraulic cylinder body fixedly installed inside the drive cavity, and the rear end of the hydraulic cylinder body is slidably connected to the rear end of the hydraulic slide rod, and the front end of the hydraulic slide rod is fixedly connected to the center of the bottom surface of the guide bracket, and inclined slide plates are fixedly connected to the left and right sides of the front of the guide bracket.

[0016] Preferably, the hydraulic mechanism includes an inclined slide plate that is slidably installed inside the front of the drive cavity, and the inclined slide plate is connected to the inclined surface at the bottom of the lifting slide rod through the inclined surface of the top surface. The left and right sides of the back of the inclined slide plate are fixedly connected to the front end of the traction steel cable, and the rear end of the traction steel cable is fixedly connected to the bottom end of the left and right side correction support seats.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This modular machining hydraulic tooling uses a displacement clamping seat and a support limiting seat to support the workpiece, and the inclined sliding plate connected to the displacement clamping seat drives the pressing protrusion to descend, so as to cooperate with the synchronously moving correction support seat to position the workpiece and avoid displacement and misalignment during clamping. The specific details are as follows:

[0018] 1. The workpiece is placed on the top surface of the support base, above the displacement clamping seat and the support limiting seat. The hydraulic cylinder is connected to the hydraulic pump, which drives the hydraulic slide rod to slide inward. This allows the hydraulic slide rod to drive the guide bracket and the internal positioning groove of the displacement clamping seat to slide inward. In turn, the displacement clamping seat drives the workpiece to achieve clamping and positioning with the support limiting seat.

[0019] The sliding guide bracket drives the inclined slide plate fixed at the front end to slide forward. The inclined slide plate gradually descends, and then the sliding rod that is attached to it contacts the limit position. The lifting slide rod that is elastically connected inside the support limit seat drives the pressing protrusion to descend and then abut against the top surface of the workpiece, preventing the workpiece from slipping upward after being subjected to force.

[0020] 2. As the inclined slide moves forward, it drives the traction cable fixedly connected to the back to be tensioned, so that the traction cable drives the correction support fixedly connected to the rear end. The correction support slides through the bottom end and passes through the correction groove. Then, it moves in the opposite direction synchronously and fits against the left and right sides of the workpiece to prevent the workpiece from shifting in the left and right directions during the positioning process.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] Example 1: In order to solve the problems existing in the use of existing hydraulic tooling for machining, this example provides a modular hydraulic tooling for machining, including a support base 1 and a drive cavity 2 opened inside the bottom surface of the support base 1; a hydraulic mechanism is provided inside the drive cavity 2 on the bottom surface of the support base 1, and the hydraulic mechanism includes a hydraulic cylinder 5, and a hydraulic slide rod 6 is slidably connected to the rear end of the hydraulic cylinder 5.

[0032] The top surface of the support base 1 is provided with a positioning mechanism, which includes a displacement clamping seat 3 and a correction support seat 4. The positioning mechanism includes a positioning slide groove 7, which is symmetrically opened on the left and right sides of the rear of the support base 1. A positioning slide rod 8 is fixedly installed inside the positioning slide groove 7, and the positioning slide rod 8 is slidably connected to the middle of the guide bracket 9. The bottom end of the displacement clamping seat 3 included in the positioning mechanism is slidably disposed inside the positioning slide groove 7. The displacement clamping seat 3 inside the positioning slide groove 7 is fixedly connected to the top end of the guide bracket 9. The guide bracket 9 is used to drive the displacement clamping seat 3 to adjust its position in the front and back directions.

[0033] like Figure 2 , Figure 5As shown, during the positioning and clamping process of the workpiece, the workpiece is placed above the support base 1, so that the front and rear ends of the workpiece are located inside the top surface of the support limit seat 11 and the displacement clamping seat 3, respectively. Then, the hydraulic cylinder 5 installed inside the drive cavity 2 is connected to an external hydraulic pump, so that the inside of the cylinder is in a continuous negative pressure state, which in turn drives the hydraulic slide rod 6 to slide into the hydraulic cylinder 5. The hydraulic slide rod 6 drives the guide bracket 9 to slide inside the positioning slide groove 7, so that the displacement clamping seat 3 at the top of the guide bracket 9 drives the workpiece to move forward and then abut against the top of the support limit seat 11, so as to prevent displacement during subsequent processing.

[0034] Example 2: In order to solve the problems existing in the use of hydraulic tooling for machining, this example adopts the following technical solution: a support mechanism is provided in front of the top surface of the support base 1, and the support mechanism includes a support limiting seat 11. The support limiting seat 11 is fixedly installed at the front center position of the top surface of the support base 1 by bolts. The left and right sides of the top surface of the support limiting seat 11 are elastically slidably connected to the lower end of the lifting slide rod 12. Moreover, the bottom end of the symmetrically arranged lifting slide rod 12 has an inclined structure and slides through the interior of the drive cavity 2.

[0035] The supporting mechanism includes pressing protrusions 13, which slide through the upper end of the lifting slide rod 12. The symmetrically arranged pressing protrusions 13 and the top of the lifting slide rod 12 are connected to each other through elastic dampers. The hydraulic mechanism includes a hydraulic cylinder 5 fixedly installed inside the drive cavity 2. The rear end of the hydraulic cylinder 5 is slidably connected to the rear end of the hydraulic slide rod 6. The front end of the hydraulic slide rod 6 is fixedly connected to the middle of the bottom surface of the guide bracket 9. The left and right sides of the front of the guide bracket 9 are fixedly connected to inclined sliding plates 14.

[0036] The positioning mechanism includes a correction groove 10, which is symmetrically opened on the left and right sides inside the bearing base 1. The correction groove 10 is slidably connected to the bottom end of the correction support 4. The correction support 4 corrects the machined components during the positioning process by moving in the opposite direction.

[0037] The hydraulic mechanism includes an inclined slide plate 14 which is slidably installed inside the front of the drive cavity 2. The inclined slide plate 14 is attached to the inclined surface at the bottom of the lifting slide rod 12 through the inclined surface of the top surface. The left and right sides of the back of the inclined slide plate 14 are fixedly connected to the front end of the traction steel cable 15, and the rear end of the traction steel cable 15 is fixedly connected to the bottom end of the left and right side correction support seats 4.

[0038] like Figures 5-7As shown, the hydraulic slide rod 6 inside the drive cavity 2 drives the guide bracket 9, which is fixedly connected at the end, to move forward during the movement. This causes the inclined slide plate 14, which is fixedly installed on the front of the guide bracket 9, to slide synchronously. At the same time, the inclined slide plate 14 abuts against the bottom end of the lifting slide rod 12 through the inclined structure at the top. This causes the unrestricted lifting slide rod 12 to drive the pressing protrusion 13 at the top to descend synchronously. The pressing protrusion 13 then presses against the left and right sides of the top surface of the front end of the workpiece, preventing the workpiece from sliding upward and causing displacement during the force process.

[0039] like Figure 3 , Figure 5 As shown, the inclined slide plate 14 inside the drive cavity 2 drives the traction steel cable 15 fixedly connected to the back to be tensioned during the sliding process. Then, the traction steel cable 15 drives the correction support 4 fixedly connected to the rear to move. The bottom end of the correction support 4 moves towards the middle outer wall of the workpiece along the left and right symmetrically opened correction grooves 10, so as to abut against the left and right sides of the workpiece for positioning and correction, and avoid the workpiece from shifting during the positioning force process.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
